Abstract
A vehicle alternator and a stator for the vehicle alternator are disclosed wherein a stator winding includes a plurality of base segments wound on slots of the stator, each of the base segments including a large segment and a small segment disposed in the same slots distanced from each other by one-pole pitch. The large and small segments have turning portions extending from one axial end of the stator to form coil ends, respectively, with the turning portions of the large and small segments being dislocated from each other in a circumferential direction of the stator core to provide a circumferential space to create a cooling wind flow path to pass cooling wind in a radial direction of the stator core.
